Advanced Filter

A reference to an empty cell is interpreted as the numeric value 0.

A matching expression can be:

• A number or logical value. A matching cell content equals the number or logical value.

• A value beginning with a comparator (<, <=, =, >, >=, <>).

  For =, if the value is empty it matches empty cells.

  For <>, if the value is empty it matches non-empty cells.

  For <>, if the value is not empty it matches any cell content except the value, including empty cells.

  Note: "=0" does not match empty cells.

  For = and <>, if the value is not empty and can not be interpreted as a number type or one of its subtypes and the property Search criteria = and <> must apply to whole cells is checked, comparison is against the entire cell contents, if unchecked, comparison is against any subpart of the field that matches the criteria. For = and <>, if the value is not empty and can not be interpreted as a Number type or one of its subtypes applies.

• Other Text value. If the property Search criteria = and <> must apply to whole cells is true, the comparison is against the entire cell contents, if false, comparison is against any subpart of the field that matches the criteria. The expression can contain text, numbers, regular expressions or wildcards (if enabled in calculation options).

Encoller / Expandir

Prema na icona Encoller para reducir o diálogo ao tamaño do campo de entrada. Así é máis doado marcar a referencia requirida na folla. As iconas convértense automaticamente na icona Expandir. Prémaa para restaurar a caixa de diálogo para o seu tamaño orixinal.

A caixa de diálogo minimízase automaticamente cando se preme co rato nunha folla. Así que se solta o botón, a caixa de diálogo restáurase e o intervalo de referencia definido mediante o rato é realzado no documento a través dun marco azul.

Diferenciar maiúsculas de minúsculas

Distinguishes between uppercase and lowercase letters when filtering the data.

Contén etiquetas de columna

Includes the column labels in the first row of a cell range.

Select the check box, and then select the cell range where you want to display the filter results. You can also select a named range from the list.

Expresión regular

Allows you to use regular expressions in the filter definition. For a list of the regular expressions that LibreOffice supports, click here.

If the Regular Expressions check box is selected, you can use regular expressions in the Value field if the Condition list box is set to '=' EQUAL or '<>' UNEQUAL. This also applies to the respective cells that you reference for an advanced filter.

The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every regular expression metacharacter or operator with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in - LibreOffice Calc - Calculate.

Ao empregar funcións nas que un ou máis argumentos sexan criterios de busca que representen unha expresión regular, téntase primeiro converter os criterios da cadea en números. Por exemplo, «.0» convértese en 0.0, etc. Se resulta ben, a busca non será unha coincidencia de expresión regular senón unha coincidencia numérica. Porén, ao traballar cunha configuración rexional na que o separador decimal non sexa o punto, como en galego, o punto fai que funcione a conversión a expresión regular. Para obrigar a que a avaliación sexa dunha expresión regular no canto dunha expresión numérica hai que empregar algunha expresión que non se poda confundir cunha numérica, como «.[0]», «.\0» ou «(?i).0».

Sen duplicación

Excludes duplicate rows in the list of filtered data.

Manter criterios de filtraxe

Select the Copy results to check box, and then specify the destination range where you want to display the filtered data. If this box is checked, the destination range remains linked to the source range. You must have defined the source range under Data - Define range as a database range. Following this, you can reapply the defined filter at any time as follows: click into the source range, then choose Data - Refresh Range.
